What VLF Hipot Test Voltage Should You Use for a 33 kV Cable?

There is no universal test voltage for every 33 kV cable. If the nameplate is 19/33 (36) kV and the approved procedure specifies 3U₀ sinusoidal VLF, the calculated level is 57 kV RMS, or approximately 81 kV peak. An 18/30 (36) kV cable would produce a different result.

SEC standartlariga muvofiq o'rta kuchlanishli kabel sinovi uchun sinov kuchlanishi qancha?

Qabulga olish va diagnostika jarayonida barcha o'rta kuchlanishli kabellar uchun juda past chastotali (VLF) sinovlari o'tkaziladi. SEC qabul qilish talablari odatda xalqaro IEEE 400.2 va IEC 60502-2 standartlari tamoyillariga asoslanadi.
